Specification of Letters Patent.

Patented Oct. 26, 1915.

Application filed August 14, 1912. Serial No.'714,9 52.

To all whom it may concern: y

Be it known that I, RICHARD M. BEDELL, a citizen of the United States, and a resident of Brooklyn, county of Kings, and State of New York, have invented a new and useful Improvement in Typographical Machines, of which the following is a specification.

My invention relates to typographical casting machines, such aslinotype machines of the general organization represented in Letters Patent of the United States, No, 436,532, to O. Mergenthaler, wherein circulating matrices are released from a magazine in the order in. which their characters are to appear in print, and then assembled in line, the composed line transferred to the face of a mold, the mold filled with molten metal to form a slug or linotype against the mat rices which produce the type characters thereon, and the matrices thereafter returned through a distributing mechanism to the magazine from which they started.

More particularly, the invention relates to the mold carrier or disk, which is ordinarily provided with two or more molds of different size, any one of which may be brought into operative relation to the other parts,.as desired. In ordinary practice, this disk is rotated by a pinion, which receives its motion from a pin or stud on a collar fast on the driving shaft, as illustrated, for instance, in Letters Patent of the United States to W. II. Randall, No. 758,103 and, in order to change the mold, it is necessarv to shiftthe pinion forward by hand, thereby disengaging it from the driving pin or stud, and then to turn it relatively to the shaft, to rotate the disk and bring another mold into operative position, after which the pinion is again engaged with the pin. In certain types of machines, when at rest and in normal {COIldltion, the ejector blade is contained wholly or partly within the mold, as illustrated, for example, in Letters Patent of the United States to J. R. Rogers, No. 945,609, wherein is also disclosed means which prevent the operation of the parts, unless the ejector blade occupies this position. In making the manual adjustment referred to, for the purpose of bringing another mold into opera tion, it sometimes happens that the mold slot does not accurately aline with the ejector blade, and, consequently, when it is attempted to move the latter forward into the slot, it will contact with the back of the mold, thus involving not only inconvenience and delay in the operation of the machine, but also resulting in injury .to the blade or to the costly mold elements. In order to obviate this difficulty, it is desirable that the mold should be made to register immediately and exactly with the other parts.

To this end, I provide supplemental means to engage the mold carrier in its'diii'erent operative positions, and specifically, these means take the form of a plurality of recesses formed in the carrier or disk, and a sprlng actuated detent adapted to engage one or another of these recesses, when the corresponding mold is in proper position.

In the accompanying drawing, I have shown my improvement as applied toa linotype machine, but obviously it iscapable of broader, application, and may be employed in variant forms, which will suggest themselves .to those skilled in the art, and in connection with other styles of typographical machines, such, for instance, as those deslgned to produce type and the like instead of slugs or linotypes, as in the present instance. Generally speaking, I desire it to be understood that I "do not limit myself to any specific form or embodiment, except in so far as such limitations are specified in the claim.

U Referring to the drawing: Figure l is a plan view, partly broken away, of the mold wheel and related parts in a linotype machine, having my invention applied thereto; and Fig. 2 is an edge view of themold wheel detached.

As in the'commercial linotype machine, the mold wheel A is of :the ordinary construction and provided with a plurality of molds 13, two of which are shown in Fig.

I. The mold wheel isactuated in the usual manner by the pinion E meshing therewith.

The pinion E is detachably connected to the shaft E and may be disconnected therefrom by the knob E to effect the adjustment of the mold wheel, in the way set forth in the said Randall patent. As shown in Fig. 1, one of the molds B is in operative relation to the ejector blade C, which advances through the mold slot to eject the slug therefrom, and to cause its passage between the trimming knives D, all in the usual manner.

As previously pointed out, in order to avoid delay and inconvenience, and injury to the parts, it is necessary, when another mold is brought into operation, that its slot should be-made to register accurately with the ejector blade. To this end I have formed a number of holding recesses or detent-engaging portions A in the side periphery of the mold wheel A, ing in number to the molds B carried by the wheel. Mounted in position to engage with these recesses A is the yielding detent or feelers member F, arranged in such manner that when the selected mold is brought into proper registration with the other parts, the detent will enter thecorresponding recess, Preferably, the detent F is formed at its end with a roll F which is held against the side of the wheel by a spring, shown in dotted lines. As the mold wheel rotates, the roll F is pressed against it until it encounters a recess A which it enters,

and thus registers the selected mold. In

addition, "the snapping of the detent into the recess is apparent to the operator rotating the wheel, by its feel or sound, or both, thus also indicating to the senses the fact that the mold is properly registered.

1 As previously stated, many variations and vmodifications of my invention will suggest tent-engaging portions corresponding in number and each bearing a definite relation to one of the molds, driving mechanism for the mold wheel adapted to be disconnected therefrom at will, manually operable means for rotating the mold wheel when disconnected from its driving mechanism to locate a difierent mold opposite theejector, and supplemental means cooperating with the mold wheel and including a mold positionthese recesses correspond- 1 during the manual rotation of the wheel to indicate to the operator that a selected mold is in predetermined registration with the ejector.

2. In a typographical casting machine, the combination of an ejector, a rotary mold wheel provided with a plurality of molds, the active one of which stands opposite the ejector, and also formed with a plurality of recesses corresponding in number to the molds and each occupying a position in predetermined relation to one of said molds, driving mechanism for the mold wheel adapted to be disconnected therefrom at will, manual means for rotating the mold wheel when disconnected from its driving mechanism to bring a difierent mold opposite the ejector, and a yielding detent mounted upon a relatively fixed support and cooperatil'lg with the mold wheel during its manual rotation to engage in one of its recesses when its corresponding mold is brought opposite the ejector, whereby the proper registration of the mold and ejector is insured.

3. In a typographical casting machine, the combination of an ejector, a rotary mold wheel provided with a plurality of molds, the active one of which is positionable opposite the ejector, and also formed with a plurality of recesses corresponding in number with the molds and each recess occupying a predetermined relation to one of the molds, manual driving mechanism for the mold wheel, and a feeler-member mounted to traverse a face of the wheel and adapted to retard movement of the same and serving, when in engagement with one of the recesses, to indicate to the operator by its retarding action that a selected mold is in registration with the ejector.

In testimonywhereof I hereunto set my hand this eighth day of August, 1912, in the presence of two attesting witnesses.
